Solar insolation is a measure of solar radiation energy received on a given surface area in a given time. It is commonly expressed as average irradiance in watts per square meter (W/m2) or kilowatt-hours per square meter per day (kWâ¢h/(m2â¢day)) (or hours/day).n an annual average the poles receive less insolation than does the equator, because at the poles the Earthâs surface are angled away from the Sun. In construction, insolation is an important consideration when designing a building for a particular climate.
